CVE-2018-3863 (GCVE-0-2018-3863)

Vulnerability from cvelistv5 – Published: 2018-08-23 15:00 – Updated: 2024-09-16 18:24
VLAI?
Summary
On Samsung SmartThings Hub STH-ETH-250 devices with firmware version 0.20.17, the video-core process incorrectly extracts fields from a user-controlled JSON payload, leading to a buffer overflow on the stack. An attacker can send an HTTP request to trigger this vulnerability. A strcpy overflows the destination buffer, which has a size of 40 bytes. An attacker can send an arbitrarily long "user" value in order to exploit this vulnerability.
Severity ?
9.9 (Critical)
